When can I apply a second coat of epoxy?

When using epoxy, it can be a helpful process to add a second layer, but you want to make sure to follow the correct procedures. With most coating epoxies, if you are trying to build up to your desired thickness, it is recommended to pour your second coat once the first coat is tacky to the touch (usually 4-6 hours).

Can you put another coat of epoxy over epoxy?

Can I put another coat of epoxy over cured epoxy? Yes. Since the epoxy has cured a chemical bond is not possible so what is called a mechanical bond is needed. This simply means that the cured epoxy has to be lightly sanded before the next coat is applied: the first coat should have a matt, almost white, surface.

Will epoxy stick to cured epoxy?

Epoxy applied over partially cured epoxy will chemically link with it and is a primary bond. The ability to chemically link diminishes as the epoxy cures and it becomes a secondary bond. Secondary bonding relies on the mechanical linking of an adhesive to a material or cured epoxy surface.

How do you apply a thin layer of epoxy?

Spread a thin layer of a well-mixed epoxy by using a squeegee first and then use a brush to finish edges. You can also use the “W” method to ensure an even finish and go over it with a back roller to reduce air bubbles and help spread out any areas which might have excess epoxy.

Can you put two coats of epoxy on garage?

Only one coat of EpoxyShield is needed on most concrete floors. If a second coat is needed / desired, it can be applied once the initial coat has dried. For the best adhesion, apply the second coat within 4 days of the first coat.

Should you sand between coats of epoxy?

First, sand down the entire surface of your piece with coarse sandpaper ( we use 80 grit sandpaper here at ArtResin ). Sanding epoxy resin between coats will not only get out the imperfection, but will also serve to provide some tooth between the first and second layers.
